Given the fact that the entire purpose of blood pressure measurement is to identify the cut-off level of blood pressure that increases the risk for cerebral, cardiac, and renal events, and that "brachial blood pressure can be an imperfect surrogate for central aortic pressure"(1), the latter being independently correlated with incident cardiovascular disease and cardiovascular risk(2), the ultimate test of the utility of the novel cuffless device is the degree to which it deviates from central blood pressure. Only 33% of conventional brachial blood pressure values have been found to lie within 5 mm Hg below or above intra-arterial values(3). The other challenge is the validity of cuffless blood pressure measurements obtained from patients with atrial fibrillation
